Abstract: PROBLEM TO BE SOLVED: To provide a high-accuracy traffic measurement analyzer.
SOLUTION: The passive measurement platform (analyzer) may be incorporated into a network router/switch or is used in conjunction with the network router/switch. The passive measurement platform receives an OSI data packet, extracts an OSI Layer 3 packet from the complete OSI data packet, extracts a header from the OSI Layer 3 packet, generates a unique packet label corresponding to the OSI Layer 3 packet, generates a timestamp, and creates a per packet record containing the headers, packet label and timestamp. The timestamp is derived from a GPS signal to minimize a problem related to frequency drift and synchronism. Data retrieval of both push model and pull model are used to conserve bandwidth of a network.

Abstract: PROBLEM TO BE SOLVED: To provide a system and method for balancing egress traffic load from a content provider between multiple service providers which can be used by the content provider. SOLUTION: The system and the method are provided for managing the allocation of the egress traffic load from the content provider 302 among the multiple service providers. Load balancing between the multiple service providers used by the content provider is performed on the basis of an analysis of traffic volume, rather than a round robin scheme or a random scheme or the like. The system is provided that comprises the content provider communicatively coupled to the multiple service providers that provide access to a communication network 301. The system further comprises an egress traffic manager 304 operable to determine, on the basis at least in part of traffic volume of each of the multiple service providers, an optimal balance of the content provider's egress traffic to be routed to each of the multiple service providers.

Abstract: PROBLEM TO BE SOLVED: To discover routing policies in networks or autonomous systems (AS) in a non-intrusive manner. SOLUTION: Discovering routing policies in information networks. Large networks such as AS are abstracted as a single network element. A plurality of taps on the borders of the abstracted element filter ingress/egress data which are forwarded for collection and correlation. By correlating information from different taps, routing policies are discovered. These discovered policies may be compared with published policies. Access control makes discovered policies and the comparisons with published policies selectively available depending on predefined access classes. COPYRIGHT: (C)2005,JPO&NCIPI

解决方案：发现信息网络中的路由策略。 大型网络（如AS）被抽象为单个网络元素。 抽象元素过滤器入口/出口数据的边界上的多个抽头被转发用于收集和相关。 通过将来自不同抽头的信息相关联，可以发现路由策略。 这些发现的政策可能与已发布的政策进行比较。 访问控制使得发现的策略和与发布的策略的比较有选择地依赖于预定义的访问类。 版权所有（C）2005，JPO＆NCIPI

Abstract: A routing monitor 200, 300, 400 is disclosed comprising at least one communication tap 203, 301, 302, 404, wherein each of the at least one communication taps is positioned in a line of communication between two routers 201, 202, 303, 304, 305, 402, 403 and a protocol emulator 204, 306, 410 for reassembling routing protocol messages captured by the at least one communication tap and opening a routing protocol connection with a network device using the reassembled routing protocol messages in response to a request for connection received from the network device.
